Abstract
The invention relates to a long crystal furnace with an improved heating construction. A first layer heater and a second layer heater of a top heater are designed and aligned according to a pyramid shape stacked by silicon raw material so as to be favorable to the primary heat absorption of the raw material. When the silicon raw material outside the pyramid shape is melted, the melted raw material directly flows among internal silicon raw material particles to accelerate the heat absorption of the internal silicon raw material so that a virtuous circle is formed to accelerate the melting and the heating of the silicon raw material in a whole crucible; a bottom heater is arranged below the crucible for heating to further accelerate the melting efficiency of the silicon raw material in the crucible, therefore, energy resources and time consumed by the long crystal furnace can be saved. Moreover, parts of the top heater and the bottom heater have corresponding shapes and can uniformly heat the crucible to save energy resources, facilitate the processing of the heaters and also save the manufacture cost.
